Need help

[Kevin Crosby]

I'm hoping someone out there can give some help--I'm doing a little paper 
about the "high magic in low puns" idea in _Lot 49_, and can't remember 
an article I read a while ago which examined TP's character names, and 
what such ridiculous names do for the reader.  Also, there's a passage in 
_GR_ I can't find either, something like "Do you know what the rate of 
change is at a cusp point?  It's infinity, folks."  Basically I'm trying 
to see how TP packs so many allusions and meanings into something so 
basic as the names of characters.  Any and all help is appreciated.
